摘要：

This work concerns the development of a time-temperature-transformation (TTT) diagram for cast CD3MN, a duplex stainless steel. Samples were solution heat treated and quenched to temperatures ranging from 700 to 900 degreesC and held for times from 1 to 1000 min. Initial sigma phase precipitation was noted as low as 700 degreesC, with the nose of the transformation curve at approximately 800 degreesC and 100 mm.
